Imagine yourself naked. Naked in a glass box suspended 15 feet in the air in an auditorium full of people. The light glaring off your naked skin. The audience completly full. Imagine the laughs of the audience, seeing every weakness, every crinkle in your polished exterior with exceptional clarity; with stark, cruel vividness.
No, really, take a moment. Reread the last paragraph and really put yourself there. Drink every word slowly and imagine every moment drawn out like an eternity.
Imagine yourself completely vulnerable. Every inch of your imperfection visible; every mask removed. Imagine every skeleton in your closet was placed openly before the world. Imagine every terrible act you've ever committed was read aloud on that stage of vulnerability to an audience of the ever judgemental and callous. Imagine, and look into the eyes of those who judge you.
And then think of the once person you could put in that auditorium who would make it all not matter.
